Maitake Mushroom (Grifola frondosa)

Maitake is an edible and medicinal mushroom grows in the northern part of the Temperate Zone in the Northern Hemisphere found in Japan, China, Europe and North America. Wild Maitake can be harvested in September and October. It forms large hands, mainly near the roots of big fagaceous trees such as white oak, beech, and tanbark oak. It grows in persimmon, plum, apricot, Prunus ume and oak trees. It invades the core of these trees. It decomposes lignin and leaves the cellulose, which is the cause of so-called white rot.

Wild Maitake has a good taste, a crisp texture, and an excellent aroma. It is considered the first-rank edible mushroom.

The scientific name of Maitake, Grifola frondosa, comes from the common name of fungi found in Italy. The name refers to a mythical beast which is half-lion and half-eagle. The Japanese name "Maitake," literally meaning "dance mushroom," is associated with its shape, which some believe resembles a dancing nymph. It is also said that people who found Maitake in a deep forest danced with joy since it was so rare and precious, which is the origin of the name.

Maitake has been prized not only for its tastes but also for its medicinal value. There have been many anecdotal reports on various medicinal properties of Maitake, and since 1980s when artificial cultivation was commercialized and Maitake became more easily available, a variety of pharmacological effects of Maitake were reported by Japanese scientists as shown below:

  • Immune boosting activity
  • Anti-tumor activity
  • Blood glucose lowering activity
  • Serum lipids normalizing activity
  • Blood pressure lowering activity
  • Hepato-protective activity
  • Weight reduction activity, etc.
